More than that, the developers believe that their technology could be used to supply electricity to remote communities and in green roofs to supply electricity to households. Unlike biogas, which is produced by the anaerobic digestion or fermentation of biomass, the Plant-Microbial Fuel Cell generates electricity while the plants continue to grow. Importantly, the researchers say the system doesn’t affect the plant’s growth of harm its environment.
